I had two previous visa refusals (Canada and the US - got the US visa later), which I disclosed in my application. Didn't seem to matter. Also, my employer made multiple mistakes in COS but corrected them in the sponsor notes. Didn't seem to matter either.

Applied for Tier-2 General extension (same employer)
Received an email after 5 days that they hadn't received my documents, even though they were delivered a couple of days earlier. Replied to the case worker with the tracking number and no response since then.
Today is the 14th day.
